Web & App Development
From $299 — Xisto designs and builds web applications with security and scalability as first principles, not afterthoughts. Every line of code is written to handle enterprise load from day one.
"Performance is an Architectural Choice, Not a Hardware Purchase."
— Shridhar Pare, Founder, Xisto Corporation
Most developers build something that works at 100 users and hope it scales. Xisto architects for 1,000,000 concurrent users from day one — using efficient query patterns, connection pooling, caching layers, and load-balanced infrastructure that grows with your traffic, not against it.
Our founder optimised a MySQL query from 15 minutes to 0.15 seconds. Built Trap17 to Top-1000 Alexa on shared infrastructure. Managed 25 engineers at Xisto Corp. That experience is in every application we build.
Architecture varies by project. We scope performance targets during briefing.
Fixed-price packages for common projects. Custom scope quoted within 24 hours.
A fast, conversion-optimised single-page site. Perfect for product launches, lead generation, and campaign pages.
A full multi-page business website with CMS, blog, contact, and optional AI advisor integration.
Custom PHP/Node.js applications with user auth, database design, REST APIs, and scalable architecture.
Ongoing development, maintenance, updates, and monitoring. Your dedicated tech team without the overhead.
Have a complex scope? Chat on WhatsApp — we'll respond with a detailed quote within 24 hours.
We use battle-tested technologies — not the latest framework hype.
PHP 8.x, Node.js, Python (FastAPI). MySQL/MariaDB with custom indexing. Redis for caching. No bloated frameworks — clean, auditable code that runs fast.
Bootstrap 5, vanilla JavaScript, and Alpine.js for lightweight reactivity. No React/Vue unless the project demands it — we don't add complexity for its own sake.
Parameterised queries, CSRF tokens, CSP headers, rate limiting, session management, and input sanitisation — built into every project by default, not bolted on later.
DeepSeek, GPT-4o, Gemini, and Claude APIs integrated natively. RAG pipelines, vector databases, and intelligent caching to keep API costs low at high volume.
Git version control, automated deployment via SSH, Nginx/Apache optimised configs, PHP-FPM tuning, and OPcache configuration — production-ready from day one.
Query optimisation, lazy loading, CDN integration, image compression, and HTTP/2. We target a PageSpeed score above 90 on every project we deliver.
You describe what you need. We ask technical questions, scope the work, and provide a fixed-price quote with a timeline.
We design the database schema, API structure, and application architecture before writing a single line of code. Security and scalability baked in from the start.
Development with regular progress updates. You review at key milestones. We incorporate feedback before moving to the next phase.
Deployed to your server or Xisto infrastructure. Full source code, documentation, and a 30-day support window included with every project.
